Mildly activated rosin fluxes are preferred. The minimum amount of solder can lead to damage from the stresses caused
by the difference in coefficients of expansion between solder, chip and substrate. The terminations are suitable for all
wave and re-flow soldering systems. If hand soldering cannot be avoided, the preferred technique is the utilization of hot
air soldering tools.

Recommended temperature profiles for re-flow soldering in Figure 1.
Wave soldering is perhaps the most rigorous of surface mount soldering processes due to the steep rise in temperature
seen by the circuit when immersed in the molten solder wave, typical at 230°C. Due to the risk of thermal damage to
products, wave soldering of large size products is discouraged. Recommended temperature profile for wave soldering
is shown in Fig. 2
Products attachment with soldering iron is discouraged due to the inherent process control limitations. In the event that
a soldering iron must be employed the following precautions are recommended.

PC board should be designed so that products are not sufficient
under mechanical stress as warping the board.
Products shall be positioned in the sideway direction against
the mechanical stress to prevent failure.
